Kohima Science College an autonomous government post graduate college is a lead institute for the approved project. The main scientific objectives of the approved projects are (i) To study the spatial and temporal (seasonal and diurnal) variability of the morphological, microphysical and rainfall properties of the precipitating systems (ii) To study the extreme weather systems in terms of these properties and atmospheric energetic.(iii) To develop a comprehensive “Precipitation Features & Atmospheric Data Base” with the help of satellite and ground based observations and (iv). To study the social impact of weather related disasters and its socio –psychological response. A total amount of Rs. 113.67 Lakhs, including the state share has been received by the college. At the outset, an eight members expert committee was formed, with Prof. Animesh Maitra, Department of Electronics & Radio Physics, Calcutta University, Kolkata as a chairman. It was followed by appointment of three research scholars and one project assistant and nomination of nine associate members for the project. The formation of expert committee, appointment of project staff and nomination of associate members have government approval. The nominated associate members are faculty members of different government colleges and institutes within and outside Nagaland. The associate members are eligible for access to the data repository developed under the project. They are also eligible for sponsorship to participate in project related academic and research activities. During the last one year, a data repository consisting of satellite data over Indian subcontinent and adjoining ocean and ground reporting of thunderstorms, hail and lightning over north eastern region during 1998- 2014 is developed. The data collection work is in progress. The data set is analyzed and a detail scientific progress report is presented along with the annual progress Kohima Science College, Jotsoma, Kohima, Nagaland, INDIA 4 report. Significant spatiotemporal variation in the properties of convective systems is observed over the study region. Few scientific results are published in a reputed journal (International Journal of Climatology, a Journal of Royal Meteorological Society UK, published by Wiley International with a impact factor of 3.61). Work is in progress to prepare more manuscripts for submission to scientific journals. Five research papers are also presented in a regional and in a international conference. Project staff including the principal investigator have participated in various training programs. Five associate members of the project are sponsored to participate in a short term course entitled “ Landslides and debris flow systems: Prediction, control and reclamation” under the Global Initiatives of Academic Network (GIAN) at Nagaland University Kohima during March 7th -11th, 2017. Two main stations, one at Kohima Science college, Kohima, Nagaland and other at Indian Statistical Institute, Giridih (Jharkhand) and twelve substations at various colleges in Nagaland are identified for placing the instruments. The work on installation of instruments at various locations is in progress. A mutual agreement is signed with Prof. Alexander G Keul, Environmental Psychology, Psychology Department, University of Salzburg, Austria to study the social impact of weather related disasters and its socio –psychological response. A set of questionnaires is developed for the analysis of socio –psychological response. A survey is in progress to collect the data in the state of Nagaland and west Bengal During the last one year, a total of Rs. 79.87 Lakhs have been utilized and balance amount is under commitment. On behalf of all the members of the project I would like to take the opportunity to present a detail progress report of the project.
